Flask-Session is an extension for Flask that adds support for server-side sessions to your application.

Install and update using pip:

$ pip install flask-session[redis]

You can include any supported storage type in place of redis.

from flask import Flask, session
from flask_session import Session

app = Flask(__name__)
# Check Configuration section for more details
SESSION_TYPE = 'redis'
app.config.from_object(__name__)
Session(app)

@app.route('/set/')
def set():
    session['key'] = 'value'
    return 'ok'

@app.route('/get/')
def get():
    return session.get('key', 'not set')
